stm32w108该如何设置组网发送字符串？请教各位大侠！
在SimpleMAC自带的的 talk.c 里，实现的是串口聊天程序。在两个PC机端各自输入什么对方就接受什么。但这个程序时点对点的，PAN ID已设定一致，即： ST_RadioSetNodeId(0x1604);ST_RadioSetPanId(0x1604);
我现在要想组网，各个节点往协调器发送自己UART接受的数据。参考 talk.c，我的程序如下。但还是没有实现，有劳GGJJ帮忙看一下，在此先谢了！
void sendSerialData(u8 length, u8 *data) //节点向SUN发送数据
{
u8 packet;
//Length
packet = (length + 11 + 2);
packet = FCF_DATA + FCF_ACKREQ + FCF_INTRAPAN;
packet = FCF_SHORTDST + FCF_SHORTSRC;
//New sequence number
currSeqNum++;
packet = currSeqNum;
//dst PAN ID
packet = (ST_RadioGetPanId()>>0)&0xFF;
packet = (ST_RadioGetPanId()>>8)&0xFF;
//Short dst addr
packet = (0xFFFF>>0)&0xFF;
packet = (0xFFFF>>8)&0xFF;
//Short src addr
packet = (ST_RadioGetNodeId()>>0)&0xFF;
packet = (ST_RadioGetNodeId()>>8)&0xFF;
//payload type
packet = PT_GENERIC_DATA; //一般数据包类型
packet = PT_CHARS; //字符串标志
halCommonMemCopy(packet+11, data, length);
txComplete = FALSE;
enqueueTxPacket(TRUE, 0xFFFF, packet, 0);
}/* end sendSerialData() */
switch(packetType) { //SUN接受到数据并输出
case (GENERIC_DATA_PACKET): //executes on SUN and PLANET
RX_DETAILS(printf("GENERIC_DATA_PACKET\r\n");)
if(rxData.packet==PT_CHARS){ //字符串标志的
for(i=12;1
